Re: 208 A Max in a 300 Weatherby
If your accumark is throated like my vanguard, I load to 3.81" with the 208s and its still .120" jump to the lands. Mine would shoot around 5/8moa at 100yrds with a 3.685" oal but shoots between 3/8and 1/2 moa with the 3.81" oal. With the 208 and the 3.685" oal I use H1000, I started with 81grns in wby brass with fed215m primers, work up in .5grn increments, may top out between 85 and 87grns at over 3k fps. If you want published data use data from the hodgdons page for the 200grn accubond as the weight and bearing surface length are very close. Good luck, be safe!
